[en] For the study and verification of this technology, it is necessary to develop the experimental facility with hot cells and auxiliary systems in the future. In this paper, several safety analysis methodologies of Korea and the United States for the development of fuel cycle facilities are introduced, and the properties of the experimental pyroprocessing facility are practically analyzed using the associated safety analysis approaches. For developing safer pyroprocessing facilities it is necessary to analyze the basic properties of these safety analysis methodologies.
